If the R9 290X was not waster that GTX 780, then it would be awfull shame for AMD, given the HW specs. Still, the performance differences are somewhat trimed down from what is expected that the hardware show. If that was speed comparsion to Titan, then well, that should be about right.
But to "just" a GTX 780? This is somewhat "slow"...

But one way or another, we are getting close to the release date. Cannot wait for well optimized drivers and BF4 using Mantle benchmark. Because if the engine is well designed for it (there is good to bare in mind, that this is the FIRST attempt to use Mantle and premiere of the Mantle itself), then there is no chance anything from nVidia come even remotely close to matching the performance.
